Only finally new shows.

To be honest, you don't need new shows at all. Stranded programmes worked in their early days when they supplemented a schedule that was primarily filled with half-hour no frills news bulletins - there was a room and a purpose for a more in-depth, regionally focussed programme every few hours that also included interviews and (in the early days) stories that wouldn't otherwise be featured. 

But once they all started becoming blocks that clogged up pretty much the whole schedule (around 2015), they became increasingly redundant. A combination of budget cuts and partially taking on the function of ordinary bulletins meant that they became less distinct and no longer added anything to the channel's output as they were the main chunk of the channel's output - at one point weekdays were going 17 hours without a standard bulletin. In that situation, as now, you only really need one brand for your programming - stick to BBC News and emphasise that you're doing the same simple news reporting all day, every day. That's a better basis for a channel than several meaningless branded programmes that differ merely in being overly interview heavy or near-exclusively interview-based.

(Worth noting, though, things on World never got as bad as the NC's utterly pointless attempts at branded news programming, which had even worse titles than the current ones).
